## Prediction

Within 24 hours, Iran is likely to test the new multinational maritime posture via non‑attributable or deniable actions such as close approaches by fast boats, unmanned surface/drone fly‑bys, and electronic interference targeting AIS or GPS signals on selected tankers, but will avoid high‑profile seizures. Such activity would aim to underline Tehran’s claim to effective control over Hormuz while remaining short of an act that would unify the new coalition behind immediate punitive strikes. Any incident will likely be localized and quickly de‑escalated by radio negotiation and coalition escort interventions. There is a smaller but present risk of an accidental collision or warning fire, which would sharply raise escalation pressure if it occurs.

## Drivers

- Iran’s demand for recognized sovereignty over Hormuz as a talk precondition
- Pattern of hybrid blockade behavior noted in emerging trends
- Recent IRGC infiltration attempt at Bubiyan indicating willingness to probe
- Kharg Island export disruption raising Tehran’s incentive to assert leverage elsewhere
